To A LL wHoM 1r MAY ooNoERN: l Be it known that I, M. H. GARDNER., of the city, county, and State of' New York, have invented a Vnew and useful Improvement in Machines for Enamelling-Paper, applicable also to enamelling'or coating other sur-faces or material, of which the following is a full, clear, and exact description, reference being had to the'aceompanying drawing, forming part ot' this specification, andv in* which- 4 Figure 1 represents a. longitudinal sectional elevation of a machine constructed in accordance with my improvement.

l Figure 2.a plan of the same.

Figure 3 represents .an inverted plan or underside view of a' portion ofari-endless beltor apron, with its gripers', as used in the machine. j i

Figures '4 and'5, transverse sections thereof, taken as indicatedby the lines a; z 'and z e in iig. `3; and

Figure 6 a longitudinal view of the brush for laying on the enamel, detached.

Similar letters of reference indicate corresponding parts.

My improvement has for itsV object the production of a'ma'chine, moreespecially designed forthe enamelling of paperwhich, while cmbracingother important features, will serve automaticallyto lay'and distribute the enamellingniixture on to the paper in an even or regular'manner, and to blend and smoothen the same over the surface as the paper or material is fedthrough and delivered from the machine in a continuous line or series of detached sheets.

My invention consists, firstly, in an enamelmixing vessel `or chamber, arranged `over the tank or chamber which supplies a. laying-on br ush,and.provided with a revolving mixing-brush, operatingin connection with stationary brushes and a distributing-screen, that has its discharge preferably controlled bypa valve or gate.

Theinvention also consists in the employment of a. travelling endless belt 'or apron, for feeding the paper or material tobe e'n-amelled, and constructed with thickened sides or edges, for guiding the apron, and restrain:

ing it from irregular expansion or contraction in direction of its width; likewise in forming the belt or apron with spaces or openings in it, fordividing the belt into lengths corresponding to the Vlengths of' the sheet being passed, and allowing of the surplus euamelling-mixture to eseapethrough the belt,'either section of which is provided at its edge with automatically-operating gripers, for holding and releasing the sheets. i

The invention also consists in constructing the drums, which carry the endless belt or apron, with grooves at or near their one end, to receive the one thickened edge of the beltin combination with adjustable or remov able rings fitted over the'drums, and serving as guides to thebelt onits opposite side or edge, and to accommodate dierent widths of belt;

Furthermore, the invention consists in a. peculiaijly-constructed supply-trunk and cylinder, in combination mixture from the trunkthrough the cylinder to thellaying-ou brush. V V

Likewise, the invention consists in a peculiar adjustable construction of the laying-on brush toaccommodateldiferent widths of paper, by` attaching its longitudinal rows of bristles, or certain of-them, to sliding bars, movable indirection of the length of the brush-stock.

with a laying-'on brush'rotati-ng in the latter, and. valves or cocksifor regulating the supplyz'ofthe enamclling.

Also, the inventiondembraccs an angular arrangement ot distributing or levelling-brush or brushes, adjustable to vary their widthvof action on the paper also, in a combination with the same, or other equivalent device or devices, of a blending-brush or brushes, which may also be lmade adjustable to suit different widths of paper.

Referring tothe accompanying drawing, A represents a mixing-chamber or vessel, preferably made detachg able from the machine, to iacilitate the putting-in andremoval or changing of the enamelling-material or composition, which is mixed'and stirredl or-worked therein, to4 give to it the requisite clearness, consistency, and uniformity, by means of a revolving brush, B, acting in'concert with stationary brushes, C, arranged on either side of the rotating brush inthe lower half of its travel, 'and preferably combining -with such devices a screen,

D, below, to exclude the passage of any foreign or coarse mat-tenand gate or slide, E, rto regulate the discharge.

of enamelling-mixture to a tank or chamber, F, and that serves to give a close bottom to the vessel A, when moving it to or from its position over thetank, or when otherwise necessary to stop the dow.

more 2 The tank er chamber F is provided, at or near its bottom, with one or more front outlets, a, that maja-it' desired, be controlled by a `gate or gates, and that answers to pass oli` the enamelling-mixturc into a trunk, G, constructed to partly surround the top and front of a horizontal cylinder, H, in which is located n. revolving brush, I', that travels as indicatedy by the arrow and is suppliedvwith enamelling-mixturc from the trunk G in a nicely-adjustable manner, as regards feed, by or through adoublcrow of intermediatcly-arranged faucets or screw stopcocks, 6, operating to cover or uncover orifices e in the periphery of the. cylinder The mixture thus taken up by the brush l is delivered or laid on the paper thro-ugh an oblong opening, d, in the cylinder H. This brush I is of peculiar construction, to give to itan expanding character, to adapt it tewerk on paper of different widths, by arranging certain of the longitudinal rows of bristles, of vwhich it is composed, on, or attaching them to sliding bars, e, made capable ofA adjustment along groovcsf inthe brush-stock or hub, said sliding bars being only of haltl or a portion ot the length of the steek, while the'ot-her, or alternate rows, g, cf `bristles, that likewise extend only a portion ot' the stock, maybe fixed or made to occupy a stationary relationship on or to the latter, so that, byslii'ting tne-hrush-slides c, that may be in single or double sets between the stationary rows g of bristles, a varied length et `operating-surf`ace isgivenA to 'the brushto" suit different widths of paper. I

The' papcr'tobe enainelled is laid or fed in. detached sheets or stripson to an .endless travelling-bolt or apron, J, at the feed-end 7i of the machine, each vsheet being clamped or held by fingers'or gripers i, as the latter, or a weighted aruuj, connected with them, strike und travel under a iixcd ruil, c. This beltdl isinadc l up in sections or with open spaces, Z, in it, for the surplus or escaping portion of the enamelling-mixturcjopass oif or through the belt into-a trough or tank, K, which prevent-s waste.l Each intervening or carrying portion of the belt, which may either beentire or of `a slatted formation, has the fingers i arranged along its advance edge by a'swingingv rod, m., connected 1.ith the weighted arin j, that, on escapingffrom under thc-fixed rail c, after the sheet has passed through `the machine, drops, tov release vhold on the sheet. Said belt may nomade 'Wholly or in part of rubberor leather, and iscaxried and driven by revolving end-drums', L, lthe one of which may be adjustable relatively to the other, to suit different lengths of belt or variations in-its stretch, while it is guided and prevented from buckling or collapsing in a transverse direction by making itsrsides or edges, 1i, of a thickened formation, the thickened edge on the one side working in grooves, o, mode in or round lic drums L nt or neartheir one end, and the other thickened edge being guided by the outer of aserics ot` rings, M, slipped on or over a reduced portion otn the body of the drum, and-which v4nii'ord a readytncans, by slipping on or oil" certain of the rings, for Working different widths of belt, according to the size of the paper to `be nnihelled.

The enamelling-lrii-xture laid on thc paper by the brush I is distributed or lcvellcd,and streaks removed from its surface, as the paper travels forward, by causing it to pass uud'cr any desired number, arranged, say, side by side, of angularly-disposod distributing or lcvclling-brushes, N, 'ormed loy, brush-bars jointed or plvoted as at'r, and capable of being raised er lowered, to'r'egulate the pressure of the brushes on the paper, also adjustable by o`r along a slotted bar, s, at their opposite ends,- nearest to the revolving brush I, and where the bars nre furthest apart, to accommodate thc said brush or brushes to ditl'erent widths of paper being ivorked. 1n rear, again, 4of these brushes N are, ermay be, anynumbcr of straight blending-brushes, l?, located, say, one in rear oflthe other, and serving to soften or blend down the enamelled suracdnnd give to it a regular and even finish, immodiatelybefrethe paper is released freni gripe by the lingers which hold it on the belt,'and which should continue to hold it till the paper or sheet is clear of. the hlending-brush-or brushes. l v

vThese last-named brushes may be adjustable one in rear of the other, widtliwise of the beltn a Somewhat similar manner to the' arrangement described for expandingor contracting the operating surface ofthe brush l, to adapt `them to different Widths of paper. v

A machine thus constructed will be found well suited to enamelling wall-paper, but is also applicable for enamelling or coating other paper or material.
